APPARATUS FOR PROTECTING WINDOWS.

SPECIFICATION forming part of Letters Patent No. 330,965, datedNovemberz l, 1885.

Application filed June 3, 1885. Serial No. 167,546. (No model.) Patentedin Germany November 7, 1884, No. 31,27l.

To all whom it may concern:

Be it known that I, EUGEN DIEZ, of Weinsberg, Germany, have invented anew and Improved Apparatus for Preventing Windows from Being Coveredwith Frost, of which the following specification is a full, clear, andexact description.

This invention relates to an apparatus for causing a thin layer or filmof a fluid to be poured down a window-pane in order to prevent thesettlement of moisture or frost upon the same.

The invention also relates to the fluid employed for this purpose.

The invention consists of the elements of improvement hereinafter morefully pointed out. I

In the accompanying drawings, Figure I is an elevation of one-half of awindow provided with my improvement. Fig. II is a vertical section online z z, Fig. I; Fig. III, a similar section on line y 3 Fig. I, on anenlarged scale. Fig. IV is a vertical section showing a modification,and. Fig. V a vertical section through the lower part of the window.

The letter A represents a window-frame. To the upper part of this frame,directly over the pane a, there is secured atrough, 1", which extendsfrom side to side of frame A. This trough is provided with trunnions x,which fit in bearings of plates t, secured to bed-plates t. By thisconstruction the trough may be oscillated, so that its lower edge isfarther away from or nearer to pane a. The trough 1' has an open back,curved front, and curved bottom,as shown. To thelower edge of trough rthere is secured a plate or strip, w, entering seats formed in plates1.. Through each end of strip 20 there passes a screw, 8, which fits ina screw-threaded perforation of strip to. On revolving screws 3 to theright or left the strip to, and with it the lower edge of trough r, isbrought nearer to or farther away from the window.

-In use a composition is poured into trough r through tube 2. and thetrough is so adjusted that athin film of liquid passes down pane a.

After it has passed down the entire pane the composition is received bya bottom trough, r, Fig. V, and flows into an outlet, (1.

In Fig. IV I have shown a modification of the invention. In this figure,ois the trough, w the strip, and a the pane of glass. Within thetrough 1) there is placed a perforated tube, 0, from which the liquid isdischarged into the trough. The liquid to be discharged through trough1* must be of such anature that it freezes at a very low temperature,Besides this, it must flow readily and be transparent, or nearly so.

I have found thata liquid composed of equal parts of glycerine andalcohol produces very satisfactory results.

I claim as my invention 1. The combination of window-frame A with trough1", extending across the same, and constructed to discharge itscontent-s over pane a, substantially as specified.

2. The combination of Window-frame A with pivoted trough r, and withset-screws s and plates 26, substantially as specified.

3. The combination of window-frameAwith pivoted trough r, plates t,strip to, and screws 8, substantially as specified.
